gradient of the line is 3
find the point on the curve where the tangent has the same gradient, (3) making it parallel
once you have that point use perpendicular distance formula
Re: HSC 2013 2U Marathon
volume of semi circle rotated about the either y or x axis from r to -r
V= \pi \int_{-r}^{r} -x^2 +r^2 dx ....... $after doing it $ V= \frac{4}{3} \pi r^3
now give what i want :)
